Great video Udarrell! The only problem I have with it is that it makes no mention to the fact that many homes have HVAC equipment that are oversized and more than the current duct system can handle, and that air sealing the duct can make this problem worse. On the one hand, they say leaky ductwork can cause a 30% to 50% loss in efficiency, but they fail to mention that by air sealing the ducts (& the home) they can then replace their equipment with smaller sized equipment that would be better sized to match the existing ductwork. Some existing equipment is only functioning BECAUSE they have leaky ductwork. Sealing the ductwork will increase the static pressure, and that will cause problems in duct systems with oversized equipment.

An answer without a question is meaningless.
Information without understanding is useless.

Right On Tips...

It is impossible to find a video that would cover all aspects the way we would cover them; but hopefully it might help folks get closer to what needs doing..,.

as to brands
Lennox
Trane
Frigidaire
York
Ruud
and on and on.
keep in mind that major brands have a lower
priced line also. for instance Trane/American Standard.

IF you need to replace ask for bids of both brands.

also ask for good better best bids.
good would minimum efficiency 13 SEER
better would be 15-17 SEER
and best (not always best but higher efficiency) 18-20 SEER.

I find the best affordable dehumidification & efficiency to be 15-17 SEER.
below that higher operating costs, above that longer payback with
little benefit.

ductwork should always be evaluated and mastic sealed.
load calc so that they don't put 400 sq ft per ton unit that
will short cycle, not remove humidity and cost you more every
month in utility costs.

nice link udarrel.

best of luck.
